Gabriel Zucman (born 30 October 1986) is a French economist known for his research on tax havens and corporate tax havens from his 2015 book The Hidden Wealth of Nations: The Scourge of Tax Havens. Zucman is also known for his work on the quantification of the financial scale of base erosion and profit shifting (BEPS) tax avoidance techniques employed by multinationals in corporate tax havens, through which he identified Ireland as the world's largest corporate tax haven in 2018. Zucman showed that the leading corporate tax havens are all OECD–compliant, and that tax disputes between high–tax locations and havens are very rare. Zucman's papers are some of the most cited papers on research into tax havens. In 2018, Zucman was the recipient of the Prize for the Best Young Economist in France, awarded by the Cercle des économistes and Le Monde in recognition of his research on tax evasion and avoidance and their economic consequences. He is currently an Assistant Professor of Economics at the University of California, Berkeley.
